From 0a087bf232c35dbec3769c4402ca737995d7b734 Mon Sep 17 00:00:00 2001 From: Madhuparna Bhowmik Date: Fri, 21 Feb 2020 21:49:47 +0530 Subject: [PATCH] net: 802: psnap.c: Use built-in RCU list checking list_for_each_entry_rcu() has built-in RCU and lock checking. Pass cond argument to list_for_each_entry_rcu() to silence false lockdep warning when CONFIG_PROVE_RCU_LIST is enabled by default. Signed-off-by: Madhuparna Bhowmik Signed-off-by: David S.
